Happy 70th First-Flight Anniversary, KC-135 Stratotanker!
On August 31, the Boeing in Washington KC-135 Stratotanker marks 70 years since its first flight in 1956, an aviation milestone with a very special Moses Lake connection. According to Air Mobility Command, the Larson Air Force Base, (now us), was more than a stop on the map: it was part of the tanker’s early test, delivery, and legacy!
Details worth celebrating
• First aircraft delivery: The first KC-135 was picked up here from Larson Air Force Base and flown to 93rd Air Refueling Squadron at Castle AFB, California.
• Project Speckled Trout: Another plane, tail number 55-3126, was nicknamed City of Moses Lake. The United States Air Force General at that time picked the aircraft up in Moses Lake and had it taken to Andrews AFB, where it helped begin Project Speckled Trout, the Air Force senior-leader transport mission that has supported every Air Force chief of staff since!
• Record-setting aircraft: The KC-135 broke two records during Operation Long Legs: a non-stop, non-refueled flight from Westover AFB, Massachusetts, to Buenos Aires, Argentina, on Nov. 11-12, 1957, and a speed record the next day from Buenos Aires to Washington, D.C.
From the Port of Moses Lake and Grant County International Airport, we salute: Happy 70th first-flight anniversary to Boeing, Air Mobility Command, and the KC-135 Stratotanker. This remarkable aircraft still gives aviation fans a reason to look up.
